"""LFM3's transformers classes, one module a model type: `native_lfm3` (text), `native_lfm3_vl` (pictures),
`native_lfm3_omni` (pictures and audio), each importing the one before it, so a Hub repository serves only its
model's files. transformers' own classes once a release ships them; until then copies of transformers' LFM3 code
beside these (each names its commit), registered with the Auto classes, so a checkpoint's config, tokenizer and
processor load and the composite models build their parts.

Shipping LFM3, transformers makes the fallbacks dead: delete them and the copies (the files headed "Vendored from"),
nothing else."""
